6-Trideoxy-L-erythro-hexose (L-amicetose)(12), 2,6-dideoxy-3-C-methyl-L-ribo-hexose (L-mycarose)(13), and 2,6-dideoxy-3-C-methyl-L-arabino-hexose (L-olivomycose)(14) have been synthesized from the corresponding lactones (9), (10), and (11), obtained, in turn, upon cleavage with ozone of the aromatic ring of suitable derivatives of the aromatic, C6–C5 optically active methyl diols (1) and (2) prepared from the C6–C3αβ-unsaturated
2,3,6-三甲氧基-L-赤-己糖(L-氨基糖)(12),2,6-二脱氧-3- C-甲基-L-核糖-己糖(L-真菌糖)(13)和2 ,6-二脱氧-3- ç甲基大号-阿糖-hexose(大号-olivomycose)(14)已经从相应的内酯(合成9),(10)和(11),得到的,反过来,在合适的芳族化合物C 6 –C 5的芳族环被臭氧裂解光学活性的甲基二醇(1)和(2)从C制备6 -C 3 αβ不饱和醛和发酵的面包酵母。
